Between a Rock and a Hard Place.An Israeli research and development firm, DM AeroSafe Group, has adapted the Eagle vertical take-off and landing (VTOL VTOL n. A convertiplane that can take off and land vertically. [v(ertical) t(ake)o(ff and) l(anding).] VTOL vertical takeoff and landing ) unmanned aircraft Unmanned Aircraft (UA) is a term used in the Federal Aviation Administration (FAA) definition of Unmanned Aircraft System (UAS). UA refers to the aircraft portion of the system required to operate it, also known as Unmanned Aerial Vehicle. and turned it into a rescue vehicle. The idea is to save people trapped beyond the reach of ladders. The Eagle VTOL aerial rescue platform's design is based on a ducted fan A ducted fan is a propulsion arrangement whereby a propeller is mounted within a cylindrical shroud or duct. The duct prevents losses in thrust from the tips of the propeller and, if the duct has an airfoil cross-section, it can provide additional thrust of its own. technology, powered by a number of internal combustion engines, on top of which a double-deck occupied area is mounted. The power plant, around which the vehicle was designed, consists of four four-cylinder radial piston aero engines with forced air cooling a. 1. In devices generating heat, such as gasoline-engine motor vehicles, the cooling of the device by increasing its radiating surface by means of ribs or radiators, and placing it so that it is exposed to a current of air.

It also potentially can be used to rescue victims of natural disasters. |
